CAR-REPLACER.

SPECIFICATION-forming part of Letters Patent No. 728,541, dated May 19,1903. Application filed October 31,1902. Serial No. 129,551. (110model.)

To ctZZ whom it may concern.-

Be it known that we, JoHN D. CAVE and JAMES F. PHILLIPS, citizens of theUnited States, residing at Indianapolis, in the county of Marion andState of Indiana, have invented certain new and useful Improvements inOar-Replacers, of which the following is a specification.

The object of our invention is to provide a pair of blocks soformed thatby properly placing them adjacent the rails of a railroadtrack they willserve to automatically replace a derailed truck upon ,.the rails whensaid truck is, drawn thereover. V

The accompanying drawings illustrate our invention.

Figure l is a perspective View showing our invention in operativeposition and a derailed truck on its way up the inclines thereof. Fig. 2is a similar view showing the derailed truck in full lines in theposition assumed immediately prior to the movement of said truck to thetops of the rails and showing said truck in replaced position in dottedlines. Fig. 3

is a perspective view of the inside replacerblock. Fig. 4 is a similarview of the outside replacer-block; Fig. 5, an end view of the blockshown in Fig. 3, and'Fig. 6 an end view of the block shown in Fig. 4. A

Ourinvention consists of an inside replacer-' block and a correspondingbut differentlyformed outside replacer-block. The inside replacer-blockconsists of a wedge shaped body 10, having formed upon-the upper face ofthe wedge a pair of tread-supports 11 -11; between which is arranged theguiding rib'12, which. guiding-rib extends upwardtofthe crown 13 of apair of downwardly-diverging replacing-inclines 14 14. Formed betweenthe rib 12 and each tread-support ll-is a groove 15, which is of a depthsomewhat greater than the height of the fiange16 of the. car-wheel. Theinclines 14 are of such height from the base that their lower edges 14shall be lower than the height of the usual railroadrail 17.

The outsidereplacer -block consists of a wedge-shaped body 18, providedwith a treadplane 19, which extends upward and forward toward a pair ofdownwardly-diverging planes 2O 20, the lower edges 20 of which arehigher than the height of an ordinary rail 17. The

crown or ridge between the two planes 20 is considerably higher than thehighest point of the tread-plane19 and extends downwardly in the form ofa guiding rib or tongue 21 a short distance upon the tread-plane 19,approximately along its medial line.

7 thetwo blocks, the tread of that wheel which lies outside the railsriding upon plane 19, the flange of this wheel passing between the block18 and the adjacent rail. The tread of the other wheel passes upon thattread plane 11 which lies adjacent the other rail, while the flange ofthis wheel passes into the adjacent groove 15, the entire weight beingsupported by the tread of the wheel, however, instead of by the flange.As the truck is drawn forward that wheel which is on plane 19 will havethe outer corner of its tread drawn upon the plane 20,which is highenough to have raised the flange of this wheel considerably above thetop of the adjacent rail, while the flange of the other wheel will passfrom-the groove 'ontothe adjacent plane 14, the truck being then in theposition shown in full lines in-Fig. 2. The inclination of planes 14 and20 is such'that when the truck reaches this position it will of its ownweight slide down to the position shown in dotted lines in Fig. 2, theheight of the incline 20 being such as to keep the flange of thecoacting wheel high enough to pass'completely over the adjacent railwithout touching it,

while the incline 14 is low enough so that as the flange slides downthis plane the tread of'this wheel will drop upon-the adjacent Ioo awedge-shaped body, a tread-incline l91ead- In Witness whereof we havehereunto set ing upward to a pair of downwardly-divergonrhands andseals, at Indianapolis, Indiana, IO ing inclines 20 the crown of saidinclines bethis 25th day of October, A. D. 1902.
